Hi Jonasx,
thanks for your reply. When I telnet to port 25 on the server from my command prompt it seems to connect OK except that no header appears and I cannot type anything in. When I go to the server and type in netstat -a | less I can see that I have established a connection. Maybe SMTP isn't working correctly??? I have done a postfix check and it came back OK. No errors starting postfix either. Sendmail has been disabled and uninstalled too so that is not accessing port 25. I have postfix running chrooted. Below id the processes that are running.
